Research has shown that air pollutants from fossil fuel use make clouds reflect more of the sun's rays back into space. This leads to an effect known as global dimming whereby less heat and energy reaches the earth. However, it is believed that global dimming caused the droughts in certain parts of the world where millions died, because the northern hemisphere oceans were not warm enough to allow rain formation. Global dimming is also hiding the true power of global warming. By cleaning up global dimming- causing pollutants without tackling greenhouse gas emissions, rapid warming has been observed and various human health and ecological disasters have resulted, as witnessed during the European heat wave in 2003, which saw thousands of people die. ______. 1). This, though, does not bring any relief in the problems associated with climate change. 2). This phenomenon thus is part of the climate change problem. 3). Scientists thus believe that this phenomenon goes hand in hand with global warming. 4). At first, it sounds like an ironic saviour to climate change problems.
The paragraph talks about how the true effects of global warming would have been on display if global dimming had not been there. So, the best concluding sentence would be option c), which says that scientists believe that global dimming goes hand in hand with global warming.
